Abstract
The invention relates to a water level controller for an air flotation machine. The water level controller comprises a handle, a screw rod, a support, a nut, a valve body, a valve element, a drainage opening and an air flotation machine box body, wherein the support is welded at the upper part on the inner side of the air flotation machine box body, and a threaded hole matched with the screw rod is formed in the support; the handle is welded at the upper end of the screw rod, and the valve body is arranged at the lower end of the screw rod; the valve element is arranged in the valve body and connected with the lower end of the screw rod; the lower part of the valve body is connected with the drainage opening through a pipeline, and the nut matched with the screw rod is arranged at the upper part of the valve body. The water level controller has the advantages of being little in investment, good in control effect and convenient to operate.
Description
Technical field
The present invention relates to water-treating equipment, particularly relate to a kind of air floatation machine water level controller.
Background technique
Air-dissolving air-float is first sent under pressure in water by air, then decompression makes the supersaturated air in water discharge with fine bubble form, thus make the impurity particle in water be sticked formation air float body, on keep afloat, under the work of Slag Scraping Device, floating mud is concentrated and sends into next procedure process.Therefore, the water lev el control of air floatation machine is most important.Otherwise water level is low, mud scum is not removed; Water level is high, and the diffluence in the lump of water and mud scum, does not reach due effect.
Summary of the invention
The present invention is solved the problems of the technologies described above by following technological means:
A kind of air floatation machine water level controller, comprise handle, screw rod, support, nut, valve body, spool, drain opening, air floatation machine casing, described support welding is on the top of air floatation machine box inside, described support has the tapped hole matched with screw rod, the upper end of described screw rod is welded with handle, the lower end of described screw rod is provided with valve body, spool is provided with in described valve body, described spool is connected with the lower end of screw rod, described valve body lower portion is connected with drain opening by pipeline, and described valve body top is provided with the nut matched with screw rod.
Further, described valve body upper side evenly has water inlet.
Further, described spool is that cover plate bottom is provided with sealing fabric, plays seal action.
Beneficial effect of the present invention: this device adopts rotation the moving up and down with movable valve plug of handle, makes water enter the method for valve body discharge drain opening.Due to when operator operates can direct vision to SEA LEVEL VARIATION, can stop draining in real time, water lev el control is accurate; Again because valve body is located at water level top, lessly in institute's draining be mixed with impurity particle and mud scum, the unblocked plug of drainage channel; This device is compared and arrange that pipeline and gate valve carry out controlling water level outside air floatation machine, and invest less, control effects is good, easy to operate.
Accompanying drawing explanation
Fig. 1 is a kind of air floatation machine water level controller schematic diagram of the present invention.
1-handle, 2-screw rod, 3-support, 4-nut, 5-valve body, 6-spool, 7-drain opening, 8-air floatation machine casing.
Embodiment
Below with reference to accompanying drawing and example, the present invention is described in detail:
A kind of air floatation machine water level controller, comprise handle 1, screw rod 2, support 3, nut 4, valve body 5, spool 6, drain opening 7, air floatation machine casing 8, support 3 is welded on the top inside air floatation machine casing 8, support 3 has the tapped hole matched with screw rod 2, the upper end of screw rod 2 is welded with handle 1, the lower end of screw rod 2 is provided with valve body 5, spool 6 is provided with in valve body 5, spool 6 is connected with the lower end of screw rod 2, valve body 5 bottom is connected with drain opening 7 by pipeline, and valve body 5 top is provided with the nut 4 matched with screw rod 2.
Further, valve body 5 upper side evenly has water inlet.
Further, spool 6 cover plate bottom is provided with sealing fabric, plays seal action.
Comprehensive the above, when this device uses, rotatable handle 1, screw rod 2 moves up, spool 6 and drainage pipe depart from, and water enters valve body 5 and discharges from drainage pipe, when water level reaches requirement, and counterrotating handle 1, screw rod 2 moves down, and spool 6 contacts with drainage pipe, and water stops discharging.
Claims (3)
1. an air floatation machine water level controller, comprise handle, screw rod, support, nut, valve body, spool, drain opening, air floatation machine casing, it is characterized in that: described support welding is on the top of air floatation machine box inside, described support has the tapped hole matched with screw rod, the upper end of described screw rod is welded with handle, the lower end of described screw rod is provided with valve body, spool is provided with in described valve body, described spool is connected with the lower end of screw rod, described valve body lower portion is connected with drain opening by pipeline, and described valve body top is provided with the nut matched with screw rod.
2. air floatation machine water level controller according to claim 1, is characterized in that: described valve body upper side evenly has water inlet.
